What's a former "High School Musical" star doing completely naked atop a toilet? That's precisely what Zac Efron wants you to to think in the new and explicit red band trailer for raunchy dude-fest film "That Awkward Moment," which explores the friendship between three pals as they hit the dating scene. (That particular moment of Efron nudity comes after his character takes too much Viagra.).
Twenty-five-year-old Efron has chosen increasingly risky roles since his Disney days, including playing Nicole Kidman's love interest in 2012's "The Paper Boy." Check out the full trailer for "That Awkward Moment" above.
